Re: [PD] OT: video camera for detection
I have tested quite few models of security cams and JVC makes some of the better ones. On most of these models you can disable AGC and get a standard fixed or zoom lens. I would recommed the auto iris unless you have 100% control of the lighting. Don't expect a great image compared to a DV camera since the security ones have none of the DSP for edge enhancement, skin tone smoothing and so on (a lot goes on in those things). Using a model with S-video output will reduce the color artifacts.

Re: [PD] OT: video camera for detection
B+W security cameras tend to have lots of manual features. Even on my elmo presentation camera I can turn off all the auto mechanisms. I've been happy dealing with elmo as a company, one of the few does not does make you agree to a license in order to get their serial control protocol. .b.

[PD] OT: video camera for detection
Hi, I am shopping for a camera or an installation. :) Detection (pix_blob, etc.) requires a camera with a pretty high resolution, and I also need to be able to disable auto gain control (AGC) and auto iris control (AIC). I guess disabling the auto white balance is a good idea too. I looked at matco.com, which has pretty afordable cameras. Their SX-920C-HR looks pretty good. It has 480 TV lines, which gives more than 720x480 pixels. See http://matco.com/pro-camera-1.htm and click on "Technical details" under that part number to see the little datasheet. I am afraid I cannot disable AGC, though at least I can use a lens which has no auto iris. Is that correct ? Do you guys think there is a way I can disable that auto iris control ? Otherwise, anyone has a camera to suggest ?
